Trip Planner — Privacy Policy

Effective date: 2026-09-10 Last updated: 2026-09-10

Summary

Trip Planner is an offline itinerary. You type your flights, trains, hotels and bookings into it, attach the confirmations, and read the day back while you are travelling. All of that stays on your phone.

There is no account, no sign-up, no cloud and no server of ours anywhere. We never see where you are going, when, or with whom.

Every time is shown in the zone of the place it happens in. A 23:40 departure typed in Jakarta still reads 23:40 after you land in Tokyo. That is a design decision about your data rather than about privacy, but it has a privacy consequence worth stating: the app stores the zone you wrote a time in, and it uses that zone for ordering and for working out how long something takes. It never asks the phone where you actually are.

Your documents are copied onto the phone, not linked. A boarding pass you attach is written into this app’s private storage, so it opens at an airport gate with no signal and no cloud account. The original stays where it was.

The only data that leaves your device is what Google AdMob needs to show ads, and none of it is anything about your trip.

Who we are

What the app stores, and where

Everything is written to this app’s private storage, which no other app on your phone can read:

That is the whole list. There is no name, no address, no photograph, no location fix and no contact anywhere in it, because the app never asks for any of them. A reference number is a string you typed for your own benefit, and the app has no idea which airline or hotel it belongs to — it never contacts one.

We hold no copy of any of it. There is no analytics SDK in this app, no crash reporter of our own, and no telemetry.

The app also opts out of Android’s cloud backup and device-to-device transfer, so your itinerary is never copied into Google’s backup service. That is a deliberate trade and you should know which way it cuts: nothing about your travel is stored off your phone, and uninstalling the app, or losing the phone, loses it. Use Save a copy before you switch phones — it is the intended way to move your data, it is never behind an ad, and for an itinerary typed off confirmation emails you may since have deleted it is the only copy there is.

About the documents you attach

This is the part most worth reading, because it is where a travel app usually gets it wrong.

When you attach a file, the app copies the bytes into its own private storage and uses the copy from then on. It does not keep a link into Google Drive, Dropbox or your Downloads folder. Two consequences:

The copy lives inside the app, so removing the entry removes the copy, and uninstalling the app removes all of them. The file is read once, through Android’s own document picker, which hands the app that single file and grants it nothing else. The app holds no storage permission and cannot see anything else on your phone.

One phone, and we say so

This app is one itinerary kept on one device. Nothing syncs. No travelling companion can see it, nobody is invited, and nobody needs an account — because there are no accounts at all.

That is a real limit and it is stated in the app as well as here, because finding it out after installing would be worse.

What the app deliberately cannot do

Worth stating plainly, because apps in this category commonly do these things:

Saving and restoring

You can save a copy of your trips and entries to a file you choose, and restore one back. A saved file leaves the app’s protection: it is written where you point it, in a readable JSON form other apps can open. The app tells you this before it writes anything.

Restoring replaces what is in the app — it does not merge — and the confirmation says so before anything is overwritten.

The file is chosen through Android’s own document picker, which hands the app that one file and grants it nothing else.

Third-party services we use

Google AdMob (ads)

The app is supported by ads served by Google AdMob. Ads are the only reason the app needs an internet connection at all; typing an itinerary, reading it, opening an attached document and working out how long a flight takes all work fully offline.

The app shows no banner ads, no native ads and no ads on launch. The only moment an occasional full-screen ad can appear is after you close an itinerary you have been planning in — never while you are reading one, and never on the way into anything. There is also an optional rewarded video you can choose to watch to switch ads off for 24 hours. Nothing in this app is locked behind it, and that includes saving a copy of your data.

To serve ads, Google receives data from your device, which may include your device’s advertising identifier (AD_ID), coarse location inferred from your IP address, device and app information, and ad-interaction data. It does not receive any trip, any entry, any reference number or any document. Google’s processing is done as an independent controller under its own policies:

Where required by law, the app shows Google’s User Messaging Platform consent form before ads are initialised, and records your choice. In the EEA and the UK you are asked about personalised advertising; in covered US states you are offered the opt-out required there. You can change your decision at any time from Settings → Ad privacy options, and if you decline, every feature of the app continues to work exactly as before.

Data we collect ourselves

None. We operate no servers, no accounts and no analytics. We have no database with your name in it and no way to identify you or your device. We do not sell or share personal information, because we do not have any.

About the times and durations in the app

The app shows the clock times you typed, in the zones you typed them in, and subtracts them to get a duration. That is arithmetic on your own figures. It is not a booking, not a confirmation and not advice: it does not know whether your flight is on time, whether it moved, or whether it exists.

Where it cannot honestly work a duration out, it says so rather than showing a zero.

Permissions the app requests

That is both of them, and there is no third. The app requests no location, no notifications, no camera, no contacts, no photo or media access, no storage permission, no calendar and no exact-alarm permission.

Seven more permissions are merged into the final app package by the libraries the app is built on, so the list Google Play shows you is longer than the two above: the advertising ID (AD_ID), the three Android Ad Services permissions, and wake-lock, foreground-service and job-service, all of which come from the Google Mobile Ads SDK and its scheduling library. None of them is a permission Android stops to ask you about, and none is used by any code we wrote.

Children

This app is not directed at children under 13 and is not designed for use under the COPPA framework. We do not knowingly collect personal information from children — as described above, we hold no personal data at all.

Your choices

Changes to this policy

If we change this policy we will update the Last updated date above and publish the new version at this URL. Material changes will also be noted in the app’s release notes on Google Play. This policy is versioned publicly in the Dash Fusion privacy repository, so any change is visible in its history.
